.ful4improvements in connection with avdei [vice of this character.

*,Vith yregard 4to .lightingv yfixtures it is a 15 well-appreciated tact,that it has `beencusto. provide an outlet box and the tocouplethefixture tothe same. Also it has .been necessaryfto resort `todisconnecting, resoldering" and insulating' the lead wires each' utimeaitixture has been removed or applied. .These operations havenecessarily involved the services of a Yskilled mechanic, 4aside h.fromthe tact that article of this character has not at alltimes beenavailable to theextent desiredQand,withthis yin view .I have conceivedof a lighting iixture, whichmay be applied or removed vbyaninexperienced personfwithout-.the necessity of opening thefeedcircuit.

A `'xurtl'ier object ,ot my invention is to providea deviceof thisnaturelwhic'h shall be' eirtremely simple `in "construction `and shallpresentcertain improvedelementsper- ,mittingof the accomplishment ot thefpurpose set forth inthe preceding paragraph. AFurther objects ofmyinveution willappeark in the "annexed ""specitication ,anddrawingspwhich latter presentone practical embodiment of t-he same, andin lwhich l Figure 1 isan enlarged cross sectional view of theconnection preferably utilized in association with the fixture.

Figures 2 and 3 illustrate details of the same.

Figure 4t is a partly sectional side view of a fixture constructed inaccordance with my invention, and

Figure 5 is a bottom plan View ot one of the details of the connection.

Having in mind, the essence of my invention, as set forth in thepreamble of this specification, I conveniently utilize as a permanentpart of a fixture. one portion of detachable connection, this portionbeing 4lucley associatedwith the box and serving' positioned adjacentthe point of connection normallyofccupied by fthe hi'clrey.

` Thus, reference being had to"Fig Lire 4, it will be seen that thereferencelnuimeral 10 indicates any 4desired 'type'of iXtur'efwhichincludes, fin vthe `embedirnei'it illustrated plug v11, secured,adjacent' its" upper end,

Awhich plug is `capable of ready association with :a socket, whereby tovprovide ineanfs'." establishinga detachable supporting'element,

and electrical connection.

`Althoug h', as afore'stated, ,any type of detachable connectionmay beutilized', ifo-r the `purpose specified I preiferablyp'employ'a plugmore particularly"`of the character illust-rated in Figure 1'.;In,tliifview'iitw'ill e noted that the lead wires Yofa thefx'tujre`10,eritehiicl lin the usualinanner beyoidl'the upper end of `the same,l centrary Ato 'the convention al construction, a 1metvallicl plug 13 issecured tothe upper end of t-lieuliiiture f10, and' forms a`ccnti'nuation ,'o'ffth'is ele ment. These t-wofrnernbers are securedwith respect tol each other ,any suitable p'niea'ns such yas attendingthe lower end of'. the

` YAlso an element i nt he` nature ot an insuwasher 16 is preferablyinterposed `17 providing insulation 1168," encircles ftliis `portion,andServes xretain `the whole in applied esta."

M Also the body ofthe plug' `llprovides a here; saltati@ rorguit@gepijpt er the-'nais 12, 'and Ione of these elementsrn'ayibeconvenllltly secured tb tliewsaine terminal "emovable tibreplug20fformed f.witl'lban opening .21hctlosing theI 1iugper endet @bei bereqi :the "Plea .18 and Lse'fvlnfg @e a supp rt forthe terminal `22 ofthe-second a layer of insulating material being preferably interposedbetween these members.

It will thus be noted, assuming that one of the feed leads 24 connectswith the socket 29, the second lead contacting with the terminal 22,that current Will be causedto flow through the leads l2, and With a viewof accomplishing this I may preferably recess the body of the plug 25 toprovide a communication space for metallic arms 31, furnishing terminals32 suitable for securing the ends of the leads 24 thereto.

It Will also be noted that one of the arms 3l extends to a point atwhich the terminal 22 vWill contact With the same When the plug isproperly7 applied to the socket, and the second arm contacts with thebody of the socket 29, thus providing the circuit desired.

From the foregoing it will be appreciated that I have provided alighting fixture Which preferably utilizes a detachable connection ofthe nature described, but not necessarily limited to this form ofconnection,

and by means of which any unskilled person may quickly eHect attachmentof any desired fixture to any outlet box, and by means of which thefixture will be properly supported and electrical connection will havebeen established. y

' Obviously numerous modifications of structure might readily beresorted to Without in the least departing from the spirit of myinvention, Which I claim as:

l. An electrical connecting device comprising a substantially solidmetallic block having a threaded plug portion for electrical andmechanical. connection with a cooperating socket, said body having anintegral flange, and means for permanently connecting said'flange to anelect-ric fixture.

2. A device recited in claim l, the body having a longitudinal passagetherethrough and a recess at its free end, an element of insulatingmaterial lodged in saidrecess and free end of the body, and .a centercontact mounted on said element.

4L. A device recited in claim l, the body having a relatively narrowlongitudinal passage therethrough, and a lead ivire binding post mountedon said body on a face of said passage, said binding post beingaccessible from the free end of the said body.

5. An electrical connecting device comprising a substantially solidmetallic block having an interiorly threaded recess capable of receivingthe conventional threaded lamp base, said block having an integralflange., an insulating body adjacent the flanged end of said block, asupport member adjacent said body, and mea-ns for mechanicallyconnecting said block, insulating 'body and support member intoa unitarystructure, said means comprising an element frictionally enga-ging saidflange.

6. A device affording electrical connection and mechanical support for aheavy electric fixture comprising a substantially solid metallic blockhaving an interiorly threaded recess capable of receiving a conventionalthreaded lamp base, an insulation body, a. support member adapted to beconnected to an outlet box adjacent said body, a flange integral withsaid block, an insulating sleeve surrounding said block, and means formechanically connectingv said block, body and support member into aunitary structure, said means comprising a metallic sleeve enclosingsaid block and frictionally engaging said flange.

7. An electrical connecting and supporting device comprising a supportmember, an insulating element adjacent said support member, a metallicblock Contact member adjacent the insulating element provided with athreaded recess and means for holding the lsupport member, insulatingelement and block in al unitary structure comprising a memberfrictionally engaging the outside of the block, in combination With ametallic block contact provided with exterior threads cooperating withsaid threaded recess, said block having a central passageway.
